New security issues


Pavel Machek
 

Hi!

My notes are below. On IRC, I wrongly assumed that "CAN BCM" refers to
some kind of driver. Unfortunately, it is generic code, and it is used
by some of our configs. This is in early stages, it is not even fixed
in Linus' tree at the moment AFAICS.

Best regards,
Pavel
